Abstract

본 발명은 스웨드조 인공피혁을 제조함에 있어서, 아민등의 산성염료와 친화력을 갖는 첨가제를 합성하여 폴리우레탄 탄성체와 혼합하고, 이를 섬유형성능을 갖는 용출후의 단사섬도가 0.5d 이하인 해도형 복합섬유로된 부직포 기포위에 충진하여 표면가공한 후, 염색하는 공정으로 이루어지는 염색성이 우수한 스웨드조인공피혁의 제조방법으로, 아민등의 산성염료와 친화력을 갖는 첨가제를 사용하여 세탁내구성이 우수하면서 색상이 선명하고 깊이가 있는 색감을 발휘한다.The present invention synthesizes an additive having affinity with acid dyes, such as amines in the manufacture of suede artificial leather, and mixed with a polyurethane elastic body, the single yarn fineness after elution having a fiber-forming ability is 0.5d or less composite fiber It is a manufacturing method of suede-bonded leather with excellent dyeability, which is a process of dyeing and filling the non-woven fabrics on the surface and then dyeing it.The additives have an affinity with acid dyes such as amines, so the washing is excellent and the color is clear. I show a deep color.
